Section 8 I/O Ports
8.16.3
The port G pins have only one special function.
8.16.4
Port G has a built-in MOS input pull-up function that can be controlled by software. This MOS
input pull-up function can be switched on or off on a bit-by-bit basis.
When a PGDDR bit is cleared to 0, setting the corresponding PGODR bit to 1 will turn on the
MOS input pull-up for that pin.
The MOS input pull-up function is off after a reset and in hardware standby mode. The prior state
is retained when in software standby mode.
Table 8.32 is a summary of the MOS input pull-up states.
